feat: Dr. Fraudsworth TradingVenue integration

[MetalLegBob]

Summary

• Replace Raydium example with Dr. Fraudsworth DeFi protocol implementation
• 6 venue instances covering 8 swap directions: 2 taxed SOL pools (CRIME/SOL, FRAUD/SOL) + 4 fixed-rate vault conversions (CRIME/FRAUD <-> PROFIT)
• Mainnet-ready: all addresses hardcoded, validated against live mainnet data + devnet TX execution

Architecture

Swaps route through the Tax Program (not the AMM directly). Tax is deducted (3-14% dynamic, epoch-dependent), then CPI into the constant-product AMM. Full CPI chain: Tax -> AMM -> Token-2022 -> Transfer Hook.

Key Details

Feature	Detail
Token standard	Token-2022 with Transfer Hook (whitelist), no Transfer Fee extension
Tax rates	Dynamic per epoch (3-14%), read from EpochState
LP fee	1% (100 bps)
Vault rate	Fixed 100:1 (CRIME/FRAUD:PROFIT)
Min output floor	50% of expected (protocol-enforced)
ALT	Protocol-wide ALT provided via AddressLookupTableTrait
Quote speed	< 100μs average (pure integer math, zero heap allocation)

Test Plan

• 21 tests in fork (8 construction + 13 quoting/parity/speed)
• 171 tests in standalone crate (full validation suite)
• 300 random log-uniform samples — zero delta vs on-chain math
• Monotonicity verified (100-step fine granularity)
• Mainnet RPC validation — real pool/epoch data
• Devnet TX execution — full CPI chain success (tx)
• Clippy clean, zero warnings
• Secret audit — zero secrets, safe for public repo
